face of sheepskin or like material is rotated and applied to the surface to be treated.

Such a polishing device has a tendency to leave circular marks or rings on the surface treated, and it is otherwise unsatisfactory.

It is the object of the resent invention to I provide a simple and .e ective polishing device adapted to resent a soft and' yielding face to the sur ace treated, and movable thereover in a direction tangential to the direction of rotation, so that the disadvantages hereinb'efore mentioned are avoided.

In carryin out the invention, I provide a plurality of iscsof fiexible mater1al lcarrying'a soft polishing material .on one face thereof. The preferred material is sheepskin with the wool thereon. The discs are mounted on a suitable arbor which is adapted for rotation, and are arranged thereon so as to forma ldrum with the wool exposed at the periphery and preferably also at the free end thereof. The discsv are arranged preferably in two or more groups, the woolcarrying faces of the respective groups being oppositely directed.' The groupsjofdiscs are held lirmly on" the arbor for rotation therewith by suitable fastening means. To expose the maximum wool surface at the periphery of the device I provide preferably means to tilt the discs of each group from planes perpendicular to the axis of the arbor.

Such means may comprise a plurality ofl Washers each having a iange bent from the plane thereof. These washers may be dis' posed on the arbor between and at the opposite ends `of the groups of discs, the flanges.

tending to dish the discs and thus to accomplish the intended purpose.

The invention will be better understood by reference toV the following detailed description and the accompanying drawings,

in which PoLIsHING DEVICE are securely held on the arbor. The disc`s'6 7 and 8 may be made of any suitable ma artificial, haiginga satisbut I prefer to' Fig. is a view in perspectiveof a device embodylng the inventlon.

device.

3 is an end view ofv the device Fig. 4 1s an elevation of the device with the parts separated. Referring to the drawings, 5 indicates'the arbor which is preferably hexagonal in form to. co-operate with similarly shaped openings 1n the discs 6, 7 and 8, so that the latter will not turn onthe arbor. At one end, a

collar 9'is internally threaded at 10 to engage the arbor and to provide a connection for the shaft of suitable driving mechanism vsuch as the shaft of shown). At the other end of the arbor I provide a washer lland a screw 12, the latter be- `mg threaded to engage an opening 13 in the end of the arbor whereby the assembled parts terial, natural o'r factory polishing surface, y employ discs of sheepskin With the wool thereon. As indicated in the drawings, I may proyide five discs 6 at the end of the arbor ad- ]acent the collar 9 With the wool ysurface thereof directed away 'from the collar. I may similarly provide four discs 7 on the arbor with the wool surface thereof rected, that is to say, opposing the wool surfaces on the five discs previously mentioned. I may then employ a single disc 8 at the end ofthe arbor with the wool surface directed oppositely to the surfaces of the discs 7.

It will be understood, of course, that the number of discs employed as hereinbefore described is merely illustrative and that any suitable number may be used, depending upon the desired size of the device and the purpose forV which it is intended.

To effect the desired exposure of the wool surface at the periphery, I employ a plurality of washers v14 having suitable openings to embrace the arbor, and flanges 15 which are bent from the plane of the washers. One of these washers'is disposed adjacent the collar 9, and two more with the fianges directed op- Fig. 2 is a longitudinal section through thev a motor or preferably a 4 `flexible shaft connected to the motor (not oppositely dipositely are placed between the first and second groups of discs. A fourth Washer isdisposed between the second group of discs and the last disc on the arbor. The effect of the flanges n the washers is to tilt the discs of each gi'oup from planes perpendicular to the axis of the support, thus exposing the maxiinum possible wool surface both at the periphery and at the free end of the device.

The polisher as thus assembled afl'ords a soft wool surface of maximum depth adapted to be applied to the surface to be treated. Wlien the device is rotated by the application of power from any suitable source, it may be applied to the' surface to be treated and moved in a direction tangential to the direction of rotation, thus ensuring maximum efficiency in the polishing operation and the avoidance of circular marks on the polished surface.

The device is simple in construction and inexpensive. The discs, when worn,^can be removed aiid replaced readily to afford a fresh and satisfactory polishing drum.

Various changes may be made in the details of construction and arrangement of the parts without departing from the invention or sacrificing any of the advantages thereof.

I claim: 1. 'A device for cleaning and polishing of groups of flexible discs each carrying wool on one face thereof mounted on the' support, the wool-carrying faces of the respective groups being op ositely directed, and means to hold the discs 1n assembled relation on the support. c

' 2. A device for cleaning and" polishing comprising arotatable support, a plurality of groups of flexible discs each carrying wool on one face thereof mounted on the support, the wool-carrying faces of the respective groups being oppositely directed, means to hold the discs in assembled relation on the support, and means to tilt the discs of each group from planes perpendicular to the axis faces are exposed at the periphery.

3. A device for cleaning and polishing comprising a rotatable support, a plurality of grou s of flexible discs each carrying wool on one acethereofmounted on the support, the Wool-carrying faces of the respective groups being oppositely directed, means to hold the discs inassembled relation on the' support, and an additional disc carrying Wool on one face thereof at the end of the device, the wool-carrying face being'directed oppositely to the corresponding faces of the adjacent discs.
